As opposed to what? They come with it preinstalled?

Correct. The factory new machine comes with Yosemite already installed.

The reason I ask is that in this forum and others, I see that many install a "fresh copy" of OS X when ever they get a factory new machine.

I understand this in the Windows world of vendor bloatware. I don't think Apple bloats their machines.

With the pending arrival of my new RiMac, I was wondering if there is a benefit to reinstalling Yosemite even though it is, at least IMO, already "factory fresh" upon delivery.

There is no reason to do that. I've never heard of people doing that. If they are they are insane. The only time I do a clean install is when a new OS comes out. That is typically because I am coming from a Developer Preview.
 
I think you may be confusing people talking about their restore from time machine and them just installing apps and files as opposed to bringing across os x settings. In effect keeping the 'clean install' and not over writing with old config files.

This.

Reinstalling Yosemite will leave your computer in precisely the condition it came out of the box.

What people are talking about is reinstalling their apps and data on this clean installation, rather than bringing across the baggage from time machine or similar. I just did this, as my previous machine is two and a bit years old and thus had four different OSs and goodness knows what bad habits lurking around...

There used to be a reason to do that because you could uncheck things like specific printer drivers and so on during the installation to save HDD space. Nowdays they are installed on demand so it's pointless to do so.

Perhaps its an old thing that still lives on?

There is a certain control factor. And given how little time it takes to do a clean install today, why not?

Now that it's no longer a bloatware issue, it's entirely down to control/security.
